An elevator passenger car including a car frame, a cage mounted to the car frame and an anti-vibration tuber member positioned between a bottom face of the cage and a lower portion of the car frame for supporting the cage. The elevator passenger car further includes a load sensing unit for measuring a passenger loading of the passenger car and a control device connected to receive the passenger loading for comparing the passenger loading with a passenger car resonance loading range to generate a control signal based on a comparison result. The elevator passenger car also includes an adjustment device positioned between the bottom face of the cage and the lower portion of the car frame for receiving the control signal from the control device and for adjusting a natural frequency of the passenger car based on the control signal by co-operating with the anti-vibration rubber member. Resonance of the passenger car with an externally applied frequency force is then avoided. A device for evaluating the feel of the ride in an elevator is further disclosed.
